Harmonic and flicker suppression device based on optimized FBD algorithm

The synthetical suppression of harmonic and flick is emphasized. Traditional FBD(Fryze -Buchholz -Dpenbrock) method is introduced and improved,based on which,the optimized FBD algorithm is designed for three -phase four -wire system by adding a feedback circuit to enhance the real -time performance of detection and dynamic response of harmonic and flicker suppression device. Based on theoretical and simulative analysis,a model of integrated harmonic and flicker suppression device with parallel active power filter is built up,which applies the optimized FBD algorithm for detection and the space vector control strategy with hysteresis loop comparator for current tracking circuit. Simulation and experiment validate the effectiveness and veracity of the detection algorithm and control strategy.
